Add orbit angle tracking related uORB values" Follow Target : Add Orbit Angle Setpoint Rate Tracking filter, to take into consideration for calculating velocity setpoint for trajectory generator for orbit angle Revert "Follow Target : Add Orbit Angle Setpoint Rate Tracking filter, to take into consideration for calculating velocity setpoint for trajectory generator for orbit angle" This reverts commit a3f48ac7652adb70baf3a2fed3ea34d77cbd6a70. Follow Target : Take Unfiltered target velocity into acount for target course calculation to fix overshoot orbit angle 180 deg flip problem Follow Target : Remove Yaw Filter since it doesn't make a big difference in yaw jitterness Follow Target : Remove velocity ramp in control & remove debug values from follow_target_status.msg Follow Target : Tidy Follow Target Status message logging code Follow Target : Remove jerk and acceleration settings from Follow Target orbit trajectory generation Follow Target : Change PublicationMulti into Publication, since topics published are single instances Follow Target : Edit comments to reflect changes in the final revision of Follow Target Follow Target : Apply incorrectly merged conflicts during rebase & update Sticks function usage for getThrottled() Follow Target : Apply final review comments before merge into Alessandro's PR Apply further changes from the PR review, like units Use RC Sticks' Expo() function for user adjustments to decrease sensitivity around the center (0 value) Update Function styles to lowerCamelCase And make functions const & return the params, rather than modifying them internally via pointer / reference Specify kFollowPerspective enum as uint8_t, so that it can't be set to negative value when converted from the parameter 'FLW_TGT_FP' Fix bug in updateParams() to reset internally tracked params if they actually changed. Remove unnecessary comments Fix format of the Follow Target code Fix Follow Perspective Param metadata follow-me: use new trajectory_setpoint msg Convert FollowPerspective enum into a Follow Angle float value 1. Increases flexibility in user's side, to set any arbitrary follow angle [deg] 2. Removes the need to have a dedicated Enum, which can be a hassle to make it match MAVSDK's side 3. A step in the direction of adding a proper Follow Mode (Perspective) mode support, where we can support kite mode (drone behaves as if it is hovering & getting dragged by the target with a leash) or a constant orbit angle mode (Drone always on the East / North / etc. side, for cinematic shots) Continue fixing Follow Target MAVSDK code to match MAVSDK changes - Support Follow Angle configuration instead of Follow Direction - Change follow position tolerance logic to use the follow angle *Still work in progress! Update Follow Me MAVSDK Test Code to match MAVSDK v2 spec - Add RC Adjustment Test case - Change follow direction logic to follow angle based logic completely - Cleanup on variable names and comment on code follow-me: disable SITL test Need to update MAVSDK with the following PR: https://github.com/mavlink/MAVSDK/pull/1770 SITL is failing now because the follow-me perspectives are no longer defined the same way in MAVSDK and in the flight task. update copyright year follow-me: mark uORB topics optional Apply review comments more copyright years follow-me sitl test: simpler "state machine" flight_mode_manager: exclude AutoFollowTarget and Orbit on flash contrained boards Remove unnecessary follow_target_status message properties - As it eats up FLASH and consumes uLog bandwidth	3 years ago
Alessandro Simovic	de1fa11e96	New follow-me flight task ... rename follow_me_status to follow_target_status enable follow_target_estimator on skynode implement the responsiveness parameter: The responsiveness parameter should behave similarly to the previous follow-me implementation in navigator. The difference here is that there are now two separate gains for position and velocity fusion. The previous implemenation in navigator had no velocity fusion. Allow follow-me to be flown without RC SITL tests for follow-me flight task This includes: - Testing the setting for the follow-me angle - Testing that streaming position only or position and velocity measurements both work - Testing that RC override works Most of these tests are done with a simulated model of a point object that moves on a straight line. So nothing too spectacular. But it makes the test checks much easier. Since the estimator for the target actually checks new measurements and compares them to old ones, I also added random gausian noise to the measurements with a fixed seed for deterministic randomness. So repeated runs produce exactly the same results over and over. Half of the angles are still missing in MAVSDK. Need to create an upstream PR to add center left/right and rear left/right options. These and the corresponding SITL tests need to be implemented later. sitl: Increase position tolerance during follow-me Astro seems to barely exceed the current tolerance (4.3 !< 4.0) causing CI to fail. The point of the CI test is not to check the accuracy of the flight behaviour, but only the fact that the drone is doing the expected thing. So the exact value of this tolerance is not really important. follow-me: gimbal control in follow-me follow-me: create sub-routines in flight task class follow-me: use ground-dist for emergency ascent dist_bottom is only defined when a ground facing distance sensor exist. It's therefore better to use dist_ground instead, which has the distance to the home altitude if no distance sensor is available. As a consequence it will only be possible to use follow-me in a valley when the drone has a distance sensor. follow-me: point gimbal to the ground in 2D mode follow-me: another fuzzy msg handling for the estimator follow-me: bugfix in acceleration saturation limit follow-me: parameter for filter delay compensation mantis: dont use flow for terrain estimation follow-me: default responsiveness 0.5 -> 0.1 0.5 is way too jerky in real and simulated tests. flight_task: clarify comments for bottom distance follow-me: minor comment improvement follow-me: [debug] log emergency_ascent follow-me: [debug] log gimbal pitch follow-me: [debug] status values for follow-me estimator follow-me: setting for gimbal tracking mode follow-me: release gimbal control at destruction mavsdk: cosmetics 💄	3 years ago
